Determination of Significance and Request for Comments on Scope of EIS

24th Street Bridge and Left Bank Project

Description of Proposal: The revised project proposes to construct a new two-lane vehicular bridge and new pedestrian trail extending from the existing cul-de-sac at 24th Street East eastward over the White River. The alignment will continue eastward until the BNSF tracks. The project also removes the existing 16’ wide pedestrian bridge and is coordinated with the proposed PSE project to minimize the clearing within the riparian area. The new bridge will be constructed at the location of an existing pedestrian bridge. It will be 55 feet and 5.5 inches wide with a 165-foot clear span over the river made up of 4 spans totaling 470 feet in length. The foundation will be drilled shafts constructed outside of the OHWM. No in-water structures and no in-water work will be required for this project. Project will include drainage facilities, utilities, construction of an access road on east side of the White River to connect to the new bridge, and realigning 24th Street East for the western bridge approach. A new alignment will occur at 142nd Street. In addition, the pedestrian path on the east side of the river will be realigned to go under the bridge and connect with the new path to the south. Flood elevation impacts created by this project will be mitigated by excavating the riverbanks back 200 feet along approximately 3 miles of the White River. All work will be done above the OHWM.
